SPEGIFIGATIQNforming part of Letters Patent No. 760,844, dated May 24,

Application filed October 27, 1903. $erial No. 178,680. (No model.) i

T0 at whom it mdy concern:

Be it known that I, PHILIP E. N EWsoM, residing at Brooklyn, in thecounty of Kings and State of New York, have invented certain new anduseful Improvements in Automatic Apparatus for Extinguishing Lights, ofwhich the following is afull, clear, and exact description, such as willenable others skilled in the art'to which it'appertains to make and usethe same. My invention relates to an apparatus for automaticallyextinguishing a gas-light at a predetermined time, although it mayb'e'used for extinguishing other kinds of" lights; It has for itsobject'to provide a simple inexpensive device of this'character thatwill operate easily and .surely. Other objects will appear from thehereinafter description."

The invention consists in certain novel features of construction; andcombination of parts, all as hereinafter fully set forth in thisspecification, and particularly pointed outinthe claims thereof.

Referring to the drawings, which form a part of this specification, andin which the same reference characters represent the same parts in thedifferent views, Figure 1 is a rear view of the apparatus attached to aswinging or Fig. 2 is asection on the line-2 of Fig. 1. Fig. 3 is asection on line 3 of Figs. 1 and 2. Fig. 4 is a detailedsectional-view,on an enlarged scale, of certain parts of the mechanism forautomatically ex- 'tinguishing the light, this section being taken onthe line 4 of Fig. 1. Fig. 5 is .a detail View of certain partsillustrated by Fig. 4, some of the .parts being in a different positionfrom that shown in Fig. 4. Fig. 6 isa front view of certain parts shownin Figs. 4 and 5.

Fig. 7 is a detailed sectional view on the line 7 ofFig. 1, showingcertain parts of the mechanism for extinguishing the light and means forstarting and stopping said mechanism. Fig. 8 is a front view of certainparts of the mechanism shown in Fig. 7, taken on the line 8 of thatfigure. The part marked 1 on the drawings repre sents the gas-pipe ofthe swinging gas-fixture. 2 is the burner, and 3 is the valve bywhichthe gas passing through the pipe is turned on and off from the burnen 4is the casing, secured to the gas-fixture. Mountedin this casing is anarbor 5, the upper end of which is bifurcated and connected to the valveThe lower end is journaled in the lower part o'f-the'casing 4, this "endpass ing through the casing-and having secured thereto the lever 6.

7 is acoiled spring, the inner end ofwhich is secured to the'arbor,andthe outer end is secured to one side of the casing by a screw 8, asshown in Fig. 2. i i

1 Ms astop or pin'projecting from the lower end of the casing andagainst which the lever rests when the apparatus is not" set forextinguishing the light. When the lever is turned from the pin, it turnsthearbor and Winds or puts the springunder'tension. Pivoted to the rearside of the casing 4 and projecting downwardly therefrom is aswingingstop 10;-

which is recessed at 11, leaving a finger 12- 14 represents the casingof the clock mech anismshown in rear view of Fig. 1, which is suspendedfrom the gas-fixture by the straps 'orr0ds15.- V I 16 represents whatcorresponds to the ordinary alarm dial-clock, having a finger or pointer17sccu'red to the arbor 18. Y Secured to the .front end of this arbor isa small disk 19, having a projection or finger 20 thereon.

21 is a gear-wheel loosely mounted on this arbor and which-has a collar22,- which is thrown over the disk 19. "Whenthis gearwheel is turned toa certain position, the pin 20 of the disk 19 bears againstthe forwardedge ofthe "collar until the gear wheel is vmoved such a position by'-the clock mech-.

anism" 'that the cam-recessi-23 in the collar 'c omes opposite the pin20, when the gearwheel and collar are thrown overthe disk. one a springsecured to the forward frame 25 of the'clock mechanism. This springrests against the inner face of the gear-fwheel 21 and tends to move thegear-wheel forward or laterally on the arbor 18. W The inner-end of- 1thisspring is-inturned, forming-afinger-26:

27 is a shaft or arbor pivoted into the front and rear frames 28 and 29of the clock mechanism. 30 is a finger secured to this arbor, and 31 isan arm also secured to the arbor and carrying a weight 32, which movesthe arbor in a certain direction. 33 is another arm secured to thisarbor, the free end of the frame being bent at right angles andextending through the slot 34 in the rear face of the clock and againstwhich the end 13 of the arm 10 rests when the mechanism is set. Thefinger 26 of the spring 24 comes in the path of movement of the finger30 and holds the arbor 27 in a set position to be described.

This apparatus operates as follows: Suppose,for example, it is desiredto extinguish the light at twelve oclock. The arbor 18 is turned untilthe hand 17 points to the hour 12, as shown on Fig. 1 of the drawings.As the arbor is moved it carries with it the disk 19, carrying thefinger 20, which forces the gearwheel 21 inwardly, thus forcing-thefinger 26 of the spring 24 over the arm 30, so that this arm cannot bemoved upwardly or the arbor 27 rock, the arm 33 being in the positionshown in Fig. 1 of the drawings. The clock mechanism is now set. Thelever 6 has moved from its stop 9 for winding up its spring, and duringthis operation the spring on the arbor 5 iswound up. The free end ofthis lever strikes against the swinging arm 10 and moves it into theposition shown in dotted lines in Fig. 1. Then the lever is released,and the free end moves in the recess 11 of this arm. The swinging armmoves backward against the arm 33 and is held in position againstfurther movement by this arm 33. The finger 12 prevents the lever 13from moving back to its original position. The parts are now as shown inFig. 1 and the gas-valve turned so thatthe gas can pass through thegas-pipe to the burner 2. At twelve oclock the gear 21 has been moved bythe clock mechanism to such position that the cam-recess 23 therein willbe opposite the finger 20 of the disk 19, at which time the spring 24throws the gear forward, and the finger 26 is carried out of the way ofthe arm 30. At this time the arm 33 no longer holds the swinging arm setwhen the lever 6 is released, and the coiled spring? turns the arbor 5,whereupon the valve 3 is turned to cut off the gas.

The means for starting and stopping the clock mechanism will now bedescribed.

40 is the arbor of the clock mechanism, to one end of which thehair-spring 41 is secured, 42 being the balance-wheel'mounted on thearbor. This balance-wheel has also secured to it the pin 43, whichmeshes with the teeth on the lever 44, mounted on the escapementarbor55, the escapement-lever being shown at '46, which is in contact withthe escapementwheel 47, mounted on the arbor 48. This arbor has securedto it the pinion 49, which is driven by a train of gears leading to themainspring. (Not shown.) Secured to the rear frame 29 of the clockmechanism is a spring 51. having an inturncd end of linger 52, which isnormally out of contact with the lever 44.

53 is a push-button extending through the rear casing of the clock andthrough the frame 29 and has an eye 54 on the forward end thereof,through which the spring 51 passes. \V hen it is desired to stop thecloekmcchanism, this push-button is pushed inwardly, when the free end52 of the spring is thrown in contact with the lever 54 and holds thelever from rocking and prevents the escapement-arbor from rocking,whereby the clock mechanism is stopped. from operating. When thepushbutton is released, the lever is permitted to rock in the usualmanner. If the mainspring of the clock mechanism is wound, but themechanism is not operating when the button is moved in and releasedquickly, the finger 52 of the spring will strike the lever 54 and rockthe lever, whereupon the escapementarbor is rocked and the mechanism isput in motion.
